The Pilot Cooling Unit (PCU) provides personal cooling when aircrew are
wearing a Liquid Cooling Vest. It provides a continuous supply temperature
controlled liquid that is circulated through the LCV, thereby maintaining the
pilot’s body core temperature.
The PCU contains a miniature vapour cycle liquid cooling system and is
capable of operation in both ground and flight conditions. Components have
been optimised to minimise size and weight. The unit operates from a 28V DC electrical supply. For ground operation, an optional Lithium Polymer
rechargeable battery pack is available.
